US Patent:

41398238, Feb 13, 1979

Filed:

Jul 18, 1977

Appl. No.:

5/816813

Inventors:

Paul N. Winters - Trumann AR

International Classification:

H03B 104
H04B 112

US Classification:

328155

Abstract:

The delay elements of a signal energy transmission network are divided into separate portions through which the transmitted energy is phase shifted by substantially equal amounts. A phase correction circuit reverses the phase shift through one of the divided delay portions by subtracting the delayed signal from the input signal of that portion to obtain a phase error signal, and then modulating the undelayed signal input to that portion with the phase error signal to reverse the phase shift caused by that same portion, so that the effect of the remaining delay portion on the phase is thereby cancelled in order to maintain a constant frequency vs. phase relationship.

International Classification:

H03B 304
H04B 336

US Classification:

331 23

Abstract:

The delay elements of a signal energy transmission network are divided into separate portions through which the transmitted energy is phase shifted by substantially equal amounts. A phase correction circuit reverses the phase shift through one of the divided delay portions by providing a locked oscillator operating at twice the frequency of the signal at a reference phase angle and subtracting therefrom the input frequency of the signal phase shifted through said one of the divided delay portions in order to maintain a constant frequency vs. phase relationship.

Appl. No.:

5/844608

Inventors:

Paul N. Winters - Trumann AR

International Classification:

H03D 306
H03K 5159

US Classification:

328155

Abstract:

A method of obtaining a constant-phase across a frequency band between points containing delay elements is shown. The delayed output is subtracted from the undelayed input in demodulators operating in quadrature to obtain quadrature phase-error signals. The phase-error signals are filtered and then additively modulated onto the delayed output with single-sideband techniques to correct the phase, thereby producing a delayed output signal that is in-phase with the undelayed signal.

Appl. No.:

5/787373

Inventors:

Paul N. Winters - Trumann AR

International Classification:

H03K 5159

US Classification:

328 55

Abstract:

The delay elements of a signal energy transmission network are divided into separate portions through which the transmitted energy is phase shifted in sequence by substantially equal amounts. A phase correction circuit reverses the phase shift through one of the divided delay portions by doubling the frequency of the signal at a reference phase angle and subtracting therefrom the input frequency of the signal phase shifted through said one of the divided delay portions in order to maintain a constant frequency vs. phase relationship.
